How to add add TextView below ListView in a DrawerLayout so that it fills width and height properly?-CodePudding

I am tasked with adding a TextView below ListView in a DrawerLayout. The TextView must stay at the bottom. I've achieved this partially (see "Request Removal" item in pic), but there are some aspects that I cannot get right. The Drawer has worked fine for a while btw. I'm just trying to modify what's there without changing too much.

As you can see the TextView is not wide enough or tall enough, allowing the blue from the background to show through.
The only way I could even get the TextView to show at bottom was by making the layout_height of the ListView to be 500dp. If layout_height stays match_parent, the new TextView won't even appear. Hardcoding a dp value here seems to be wrong. I hardcoded a layout_height for the TextView hoping it would "push up" against the ListView so that the TextView could appear, but no workie.

The layout is below too.

How do I properly modify my layout so that the TextView with "Request Removal" appear at bottom without the ugliness?

The solution is simply to remove these two lines from the layout of the problematic TextView. Duh.

    android:layout_marginLeft="15dp"
    android:layout_marginBottom="7dp"
